FURNITURE-*CASTER.

SPECIFICATION forming part of Letters Patent N 0. 679,849, dated August6, 1 901.

Application filed'February 2, 1901. Serial No. 45,727. (No model.)

To all whom it may concern.-

Be it known that I, BERTRAND P. KENYoN,a citizen of the UnitedStates,residing at Grand Rapids, in the county of'Kent and State ofMich'igamhaveinvented certain newand use ful Improvements inFurniture-Casters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in furniture-casters, and moreparticularly to that class of casters in which the yoke is j ournaled ona non-rotat-ive pin fixed in the furniture.

The object of my invention is to provide a yoke of improved constructionthat can be made of a single piece of sheet metal and that will bestrong and durable and to provide the device with certain new and usefulfeatures hereinafter more fully described,and particularly pointed outin the claims.

My invention consists, essentially, in the peculiar construction of theyoke, as hereinafter more fully described, reference being had to theaccompanying drawings,in which Figure 1 is a side elevation of a pin anda vertical section of the yoke on the line 1 1 of Fig. 2. Fig. 2 is aplan View of the same. Fig. 3 is a plan of the blank from which the yokeis formed, and Fig. 4 a detail in side elevation of the yoke whencompleted.

Like letters refer to like parts in all the figures. I

A represents the pin, having its upper part adapted to be fixed in anarticle of furniture and provided with a circumferential enlargement orcollar A, adapted to engage the lower end of the furniture-leg at itsupper side and to engage and form a bearing for the head of the yoke.The yoke is journaled on the lower end of the pin A, ashereinafterdescribed.

The yoke consists of a'single piece of sheet metal made from a blankhaving the outline shown in Fig. 3. This blank has a substantiallystraight middle portion 0, adapted to form the head of the yoke, and twoarms B B, diagonally projecting from the opposite sides andat one end ofthe middle portion and adapted to form the parallel arms of the yoke toembrace the caster-wheel and support the journal of the same. The end ofthe middle at each side to engage the plate at each side of of the saidrecess. The middle portion 0 is also provided with openings to receivethe pin A,

located within the portions adapted to form the top and bottom portionsof the head and at one side ofthe portion connecting the arms,surrounding which openings are bosses E E, to increase thebearing-surface on the pin. A bead D is also raised around the upperopening to engage and form a bearing for the collar A on the pin. Thisblank is formed by folding it at substantially right angles along thedotted lines shown on Fig. 3, the arms B B being turned into parallelplanes and toward one side of the plate forming the blank and the middleportion turned toward the opposite side of the blank and engaging thereduced end G with the recess G. The middle portion of the blank thusforms the top, bottom, and two sides of a substantially square headperforated at the top and bottom to receive the pin and having the armsB B projecting from one side. In use the strain tends to pull the headaway from the arms at the lower side where it is jointed integrallytherewith and not easily severed by such strain. At the top of the armsthe strain tends to crowd the reduced portion G and the shoulders F intoengagementwith the recess G and the side of the plate, and thus there isno occasion to otherwise secure the parts together, the shoulders Feffectually sustaining the pressure at this point. I thus secure a verystrong and durable structure at small expense of manufacture.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. A blank for caster-yokes, substantially T-shaped in outline, andconsisting of a middle part adapted to form the top, bottom and twovertical sides of a substantially square head, and having a recess atone end and a shouldered opposite end adapted to engage the recessedend; and two arms projecting oppositely, and diagonally from therecessed end, substantially as described.

2. In a caster-yoke a head formed of a conangle, substantially asdescribed.

tin uoi'ls strip of sheet metal bent transversely at right angles inthree places, to form the top, bottom and two vertical sides of asubstantially square head the ends of said strip being joined at anupper angle of the head; and two integral arms projecting from thevertical side of the head adjacent to said 3. In combination with a pinhaving a circumferential enlargement, a yoke rotativeon the pin, andformed of a single piece of sheet metal, having a middle portionperforated to receive the pin, and having bosses, and a bead surroundingthe perforations, said mid- BERTRAND P. KEnYoN. Witnesses:
